Date rape drug (GHB) or rohypnol?

Some of you may have heard recently about the mother of 2 in the UK raped by 3 teenagers (1 who was 14, the other 2 16yrs old)

http://news.sky.com/skynews/article/0,,3...

However, somethings dont quite add up as ive looked into this further

a) She states her audeal lasted 14hrs
Wikipedia states the date rape drug tends to last about 1.5 - 3hrs depending on the dosage sometimes longer (surely not an extra 11hrs)

b) She says she suddenly felt weird and numb shortly after drinking champagne and suspects it was spiked
But for it to have a quick effect it must be 3500mg or higher which is near lethal dosage (7000mg is life threatening)
Surely even if it was hodourless something would have been notisable

Woudl a hair follicle test prove if a drug was induced

some people are skeptical it may be a cover up since the video went public, and may worry about being done for having sexi with minors and it was voluntary

Please help

I don't think it was consensual ...the guy peed on her and they did it with her darn kids screaming and i believe watching!!!
Those guys should be hung!!!

hair folicle test, blood test, rape kit test... there are a lot of ways forensics can determine what actually happened. Give it time, the authorities will figure it out no doubt.

my question,, why was she drinking champane with teenagers in her house while her kids were there?

and if she was somewhere else, why was she drinking champane, when she was caring for her children

whats the teenagers did was wrong yes, but she put herself in that situation

The effects of flunitrazepam appear approximately 15 to 20 minutes after oral administration, and last for approximately four to six hours. Some residual effects can persist up to 12 hours or more after administration, also who said she wasn't administered more after 4 or 5 hours ?
